1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: C3 glomerulopathy (C3G) is a complex, chronic, ultra rare, progressive primary glomerulonephritis, resulting from alternative complement pathway overactivation, leading to kidney failure in most patients, and frequent recurrence in transplants. Iptacopan (LNP023) is an oral, proximal complement inhibitor specifically targeting factor B, that selectively inhibits the alternative complement pathway. Methods: This was a phase 2 extension study of 26 adult patients with native kidney (cohort A), or recurrent C3G (post kidney transplantation; cohort B) receiving open label iptacopan. Results: At 12 months, patients in cohort A had a significant reduction in 24-hour urine protein-to-creatinine ratio (UPCR; 57%; Conclusion: These data provide a clinical rationale for further evaluation of long-term treatment of C3G with iptacopan.
